Five Ways to Compute an STFT on a Qualcomm SoC: Accuracy, Latency, and Power, Measured Not Guessed
A Qualcomm engineer measured five Short-Time Fourier Transform (STFT) implementations on a Snapdragon SM8650 test unit, finding that CPU and DSP backends achieve near-zero error against a NumPy refere…
